Gun type: in accordance with the shape design of human body engineering, ultrasonic start switch is located on the trigger, easy to grasp and use the welding operation, especially suitable for horizontal or vertical.
Cylinder type: for the appearance of design straight, ultrasonic start switch is located outside the cylinder, easy welding and hand carried, can also be installed between the on machine, welding operation for each direction.
Advantages and Disadvantages of Ultrasonic in Auto Industry.
Advantages:
- Equipped with welding timer
- Light weight, easy to take, easy to operate (handheld)
- Easty to set time welding
- Application in riveting, forming and welding
- Equipped with an overload protection circuit( Voltage, current, phase, temperature, output
- Maintain the amplitude function automatically
- Starting: achieving maximum power with 105msec
Disadvantages:
Limitation of measure, shape and material.(ultrasonic welding for PP, PC, ABS, PA, PS, AMMA plastic).
Affacting Factors in Dashboard Welding:
With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.Pa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.
The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds. Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds. AMMA plastic).
Different Applications of Ultrasonic Spot Welder
Ultrasonic welding: ultrasonic vibration with ultrasonic welding mould, the ultrasonic welding energy conduction to the plastic surface, resulting in local temperature, so that the plastic surface melting. Under the pressure of the ultrasonic hand, so to weld plastic, beautiful, strong effect.
Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
Different Types of Horn
Titanium
high price, excellent performance good toughness and low loss, difficult to be processed;
Its amplitude can reach to 60mm.
Aluminum
low price, fast loss, easy to be processed;
Its highest amplitude less than 300mm.
Steel
too hard to be made as horn;
its highest amplitude less than 25mm;
It is suitable for cutting but the blowpipe need to be added in for its cooling.
